AstraZeneca vaccine 79% effective in U.S. trial, panel finds no higher risk of clots

FRANKFURT:  AstraZeneca and Oxford University's COVID-19 vaccine was 79% effective in a large U.S. trial at preventing symptomatic illness, and was 100% effective against severe or critical disease and hospitalisation, the drugmaker said on Monday.

The fresh data comes after many countries resuming use of the vaccine after the European Medicines Agency (EMA) and the World Health Organization (WHO) said the benefits outweighed the risks following investigations into reports of blood clots. AstraZeneca said an independent safety committee conducted a specific review of the blood clots in the U.S. trial, as well as cerebral venous sinus thrombosis (CVST), which is an extremely rare blood clot in the brain, with the help of an independent neurologist.
